DEMO MANUAL DC1523A

LTC3789EGN:

High Efficiency Synchronous

4-Switch Step-Up/Step-Down

DC/DC Converter

DESCRIPTION

Demonstration circuit 1523A features the LTC

3789EGN,

a high efficiency switching step-up/down controller. The

DC1523A input range is from 5V to 36V. The output volt-

age is 12V. The board is capable of delivering up to 5A of

output current over the input voltage range.

The LTC3789EGN is a high performance switching regula-

tor controller designed to regulate the output using input

voltages above, below or equal to the output voltage.

Synchronous operation provides very high efficiency, up

to 97%. Constant frequency current mode architecture

allows phase-lockable frequency from 200kHz to 600kHz.

An accurate output current limit provides support for

battery charging. A wide input and output range with

smooth transfer function through all operating modes

makes the product ideal for automotive, telecom and

battery systems.

The MODE/PLLIN pin can select between pulse skipping

mode and forced continuous mode operation and allows

the IC to be synchronized to an external clock. A Power

Good output pin indicates when the output is within 7.5%

of its set point.
